<p>PROBLEM TO BE SOLVED: To prevent a galling and a friction nozzle from occurring between a boss part and a sliding plate and a bracket part and the sliding plate by increasing the lubricating performance therebetween. SOLUTION: The sliding plate 23 is disposed between the boss part 15 and the bracket part 17 on the outer peripheral side of a connection pin 19. Also a molybdenum disulfide treated layer 24 and a molybdenum disulfide treated layer 25 are formed on the end face 15C of the boss part 15 and the end face 17C of the bracket part 17, respectively. Then, the end faces 23A and 23B of the sliding plate 23 are brought into contact with the molybdenum disulfide treated layers 24 and 25, respectively.</p> |
